The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - scsi: target: core: Add TMF to tmr_list handling An abort that is responded to by iSCSI itself is added to     tmr_list but does not go to target core.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004872 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    scsi: target: core: Add TMF to tmr_list handling

    An abort that is responded to by iSCSI itself is added to tmr_list but does     not go to target core. A LUN_RESET that goes through tmr_list takes a     refcounter on the abort and waits for completion. However, the abort will     be never complete because it was not started in target core.

    To fix this, only add abort to tmr_list if it will be handled by target     core.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6821-3 advisory.

    It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition,     leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or     possibly execute arbitrary code. (CVE-2023-6270)

    It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data     structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial     of service. (CVE-2023-7042)

    It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer     dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service.
    (CVE-2024-0841)

    Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race     condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of     service (system crash). (CVE-2024-22099)

    It was discovered that the MediaTek SoC Gigabit Ethernet driver in the Linux kernel contained a race     condition when stopping the device. A local attacker could possibly use this to cause a denial of service     (device unavailability). (CVE-2024-27432)
